    the electric potential in the sphere is 3.88 X 10⁴ Volts

    Explanation:

    Electric potential is given as;

    V = kq/r

    where;

    q is the charge present in the sphere = 0.66 µC

    k is coulomb's constant = 8.99 X 10⁹ C

    r is the radius of the sphere = 15.5 cm = 0.155 m

    V = (8.99 X 10⁹ * 0.66 X 10⁻⁶) / 0.155

    V = 3.88 X 10⁴ Volts

    Therefore, the electric potential in the sphere is 3.88 X 10⁴ Volts

    The electric potential in the sphere is 3.9 X 10⁴ V.

    Explanation:

    Electric potential, V = kq/r

    where,

    q = charge

    = 0.66 µC

    k = coulomb's constant

    = 8.99 X 10⁹ C

    r = radius of the sphere

    = 15.5 cm

    = 0.155 m

    V = (8.99 X 10⁹ * 0.66 X 10⁻⁶) / 0.155

    = 3.9 X 10⁴ V.
